Abstract

Bei einem Verdichter mit axial geteiltem Gehäuse, bestehend aus mehreren Gehäusehälften (21a, 21b), sind die Leitschaufeln (1) mit ihren Füssen (3) in Umfangsnuten (10) befestigt. Ueber den Umfang verteilt sind im Nutgrund der Umfangsnut (10) verankerte Bolzen (8) eingebracht. Diese Bozen (8) ragen vorzugsweise radial in die Umfangsnut (10) hinein und unterteilen die Leitschaufeln (1) in Gruppen (A4, A5) und an der Trennebene (20) des Gehäuses (21a, 21b) liegende Abschluss-Gruppen (A6, A7).

Figure 00000001
In the case of a compressor with an axially divided housing, consisting of a plurality of housing halves (21a, 21b), the guide vanes (1) are fastened with their feet (3) in circumferential grooves (10). Bolts (8) anchored in the groove base of the circumferential groove (10) are distributed over the circumference. These bolts (8) preferably protrude radially into the circumferential groove (10) and divide the guide vanes (1) into groups (A4, A5) and end groups (A6, A7).
